Not taste. It tests whether a candidate can hold a design together under examination: whether the plan solves the brief, whether the section could be built, whether the loads go anywhere, and whether the details keep water out. The examiner reads for consequence — a corridor that cannot be escaped from, a flat roof with no fall, a column that has become a window, a bathroom with no vent — and a candidate who has drawn without deciding loses on all four counts within a page. So the method matters more than the composition. Establish the requirements and their areas; stack the rooms by the relationship the users actually have, not by the diagram's symmetry; give the building its spine and its two or three ways out; put the structure on a grid that the services and the façade can share; and then test the result against three questions in order: can a user find their way, can a builder build it, and can the environmental strategy carry it without a machine for every degree? A design that answers those three survives the viva; one that only looks resolved does not.

A brief is a set of numbers and a set of conflicts, and the professional act is to name both. Room schedule with areas and occupancies, the relationships that must be direct and the ones that must be separated (a kitchen against a treatment room, a generator under a bedroom), the budget and the maintenance level the client can actually sustain, and the phasing the client has not yet noticed. The site analysis then converts the constraints into design decisions: the sun path and the season it hurts, the prevailing wind and the dusty harmattan that argues for a filtered lobby, the water table and the flooding that decides whether the ground floor can hold plant, the noise and the neighbours that decide where the quiet rooms go, and the access points a fire appliance can actually reach and turn in. The parti is the sentence the whole scheme can be checked against — 'a linear clinic on a spine with a waiting hall at the near end and an isolation wing that can be closed off' is a parti; 'an airy modern building with a strong entry' is not, because nothing could be tested against it. Draw the parti as a bubble diagram, then as a massing section, then as a plan: at every translation ask which requirement it answers. A candidate who can say in the viva 'I placed the circulation here because the brief needed the two wings separable during an outbreak' has demonstrated the thing being examined — the reason, not the drawing.
